Achieving benchmarks for national quality indicators reduces recurrence and progression in non-muscle-invasive bladder cancer

Background Noncompliance with evidence-based interventions and guidelines contributes to significant and variable recurrence and progression in patients with non–muscle-invasive bladder cancer (NMIBC). The implementation of a quality performance indicator (QPI) programme in Scotland’s National Health Service (NHS) aimed to improve cancer outcomes and reduce nationwide variance. Objective To evaluate the effect of hospitals achieving benchmarks for two specific QPIs on time to recurrence and progression in NMIBC. Design, setting, and participants QPIs for bladder cancer (BC) were enforced nationally in April 2014. NHS health boards collected prospective data on all new BC patients. Prospectively recorded surveillance data were pooled from 12 collaborating centres. Intervention QPIs of interest were (1) hospitals achieving detrusor muscle (DM) sampling target at initial transurethral resection of bladder tumour (TURBT) and (2) use of single instillation of mitomycin C after TURBT (SI-MMC). Outcome measurements and statistical analysis The primary and secondary endpoints were time to recurrence and progression, respectively. Kaplan-Meier and Cox multivariable regression analyses were performed. Key findings and limitations Between April 1, 2014 and March 31, 2017, we diagnosed 3899 patients with new BC, of which 2688 were NMIBC . With a median follow up of 60.3 mo, hospitals achieving the DM sampling target had a 5.4% lower recurrence rate at 5 yr than hospitals not achieving this target (442/1136 [38.9%] vs 677/1528 [44.3%], 95% confidence interval [CI] = 1.6–9.2, p = 0.005). SI-MMC was associated with a 20.4% lower recurrence rate (634/1791 [35.4%] vs 469/840 [55.8%], 95% CI = 16.4–24.5, p < 0.001). On Cox multivariable regression, meeting the DM target and SI-MMC were associated with significant improvement in recurrence (hazard ratio [HR] 0.81, 95% CI = 0.73–0.91, p = 0.0002 and HR 0.66, 95% CI = 0.59–0.74, p < 0.004, respectively) as well as progression-free survival (HR 0.62, 95% CI = 0.45–0.84, p = 0.002 and HR 0.65, 95% CI = 0.49–0.87, p = 0.004, respectively). We did not have a national multicentre pre-QPI control. Conclusions Within a national QPI programme, meeting targets for sampling DM and SI-MMC in the real world were independently associated with delays to recurrence and progression in NMIBC patients. Patient summary Following the first 3 yr of implementing a novel quality performance indicator programme in Scotland, we evaluated compliance and outcomes in non–muscle-invasive bladder cancer. In 2688 patients followed up for 5 yr, we found that achieving targets for sampling detrusor muscle and the single instillation of mitomycin C during and after transurethral resection of bladder tumour, respectively, were associated with delays in cancer recurrence and progression

The comparison of imaging and clinical methods to estimate prostate volume: a single-centre retrospective study

Background: Prostate volume (PV) is a useful tool in risk stratification, diagnosis, and follow-up of numerous prostatic diseases including prostate cancer and benign prostatic hypertrophy. There is currently no accepted ideal PV measurement method. Objective: This study compares multiple means of PV estimation, including digital rectal examination (DRE), transrectal ultrasound (TRUS), and magnetic resonance imaging (MRI), and radical prostatectomy specimens to determine the best volume measurement style. Methods: A retrospective, observational, single-site study with patients identified using an institutional database was performed. A total of 197 patients who underwent robot-assisted radical prostatectomy were considered. Data collected included age, serum PSA at the time of the prostate biopsy, clinical T stage, Gleason score, and PVs for each of the following methods: DRE, TRUS, MRI, and surgical specimen weight (SPW) and volume. Results: A paired t test was performed, which reported a statistically significant difference between PV measures (DRE, TRUS, MRI ellipsoid, MRI bullet, SP ellipsoid, and SP bullet) and the actual prostate weight. Lowest differences were reported for SP ellipsoid volume (M = −2.37; standard deviation [SD] = 10.227; t[167] = −3.011; and p = 0.003), MRI ellipsoid volume (M = −4.318; SD = 9.53; t[167] = −5.87; and p = 0.000), and MRI bullet volume (M = 5.31; SD = 10.77; t[167] = 6.387; and p = 0.000). Conclusion: The PV obtained by MRI has proven to correlate with the PV obtained via auto-segmentation software as well as actual SPW, while also being more cost-effective and time-efficient. Therefore, demonstrating that MRI estimated the PV is an adequate method for use in clinical practice for therapeutic planning and patient follow-up

Renal tumor biopsy for small renal masses: a single-center 13-year experience

BACKGROUND: Renal tumor biopsy (RTB) for the characterization of small renal masses (SRMs) has not been widely adopted despite reported safety and accuracy. Without pretreatment biopsy, patients with benign tumors are frequently overtreated. OBJECTIVE: To assess the diagnostic rate of RTBs, to determine their concordance with surgical pathology, and to assess their impact on management. DESIGN, SETTING, AND PARTICIPANTS: This is a single-institution retrospective study of 529 patients with biopsied solid SRMs ≤4cm in diameter. RTBs were performed to aid in clinical management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Diagnostic and concordance rates were presented using proportions. Factors that contributed to a diagnostic biopsy were identified using a multivariable logistic regression. RESULTS AND LIMITATIONS: The first biopsy was diagnostic in 90% (n=476) of cases. Of the nondiagnostic biopsies, 24 patients underwent a second biopsy of which 83% were diagnostic. When both were combined, RTBs yielded an overall diagnostic rate of 94%. Following RTB, treatment could have been avoided in at least 26% of cases because the lesion was benign. Tumor size and exophytic location were significantly associated with biopsy outcome. RTB histology and nuclear grade were highly concordant with final pathology (93% and 94%, respectively). Adverse events were low (8.5%) and were all self-limited with the exception of one. Although excellent concordance between RTB and final pathology was observed, only a subset of patients underwent surgery following biopsy. Thus it is possible that some patients were misdiagnosed. CONCLUSIONS: RTB of SRMs provided a high rate of diagnostic accuracy, and more than a quarter were benign. Routine RTB for SRMs informs treatment decisions and diminishes unnecessary intervention. Our results support its systematic use and suggest that a change in clinical paradigm should be considered. PATIENT SUMMARY: Renal tumor biopsy (RTB) for pretreatment identification of the pathology of small renal masses (SRMs) is safe and reliable and decreases unnecessary treatment. Routine RTB should be considered in all patients with an indeterminate SRM for which treatment is being considered

Enhanced Quality and Effectiveness of Transurethral Resection of Bladder Tumour in Non–muscle-invasive Bladder Cancer:A Multicentre Real-world Experience from Scotland's Quality Performance Indicators Programme

Background: Clinical outcomes from non–muscle-invasive bladder cancer (NMIBC) are partly determined by the quality of initial interventions. To improve and standardise treatment for cancer, Scotland implemented a national Quality Performance Indicator (QPI) programme for bladder cancer (BC). Objective: To evaluate compliance with specific quality indicators (QIs) related to transurethral resection of bladder tumour (TURBT) and to understand clinical outcomes from NMIBC following the introduction of the QPI programme. Design, setting, and participants: Within a robust governance framework, 12 mandatory evidence-based QPIs were implemented nationally in April 2014. We report prospectively collected data for all new BC patients (between April 2014 and March 2017). We include follow-up data for 2689 patients. Intervention: The TURBT-related QPIs were (1) using a bladder diagram, (2) single post-TURBT instillation of mitomycin C (SPI-MMC), (3) detrusor muscle (DM) in the specimen, and (4) early re-TURBT in high-risk NMIBC. Outcome measurements and statistical analysis: We measured compliance with these QPIs and (1) recurrence rate at first follow-up cystoscopy (RRFFC), (2) rates of residual cancer, and (3) pT2 cancer at re-TURBT. Associations between QPI compliance, tumour features, and outcomes were assessed with multivariable logistic regression models. Results and limitations: Among 4246 new BC patients, SPI-MMC was used in 67% (2029/3023) NMIBC patients. In 1860 NMIBC patients undergoing TURBT, RRFFC, rate of residual cancer, and rate of pT2 at re-TURBT were 13% (116/888), 33% (212/653), and 2.9% (19/653), respectively. SPI-MMC was associated with lower RRFFC, independent of all variables including hospital volume and surgeon. Presence of DM in the specimen halved the likelihood of residual disease in pT1 cancers. The main limitation is the lack of a pre-QPI introduction cohort for comparison. Conclusions: The implementation of a QI programme in Scotland appears to facilitate high-quality TURBT, which in a real-world setting is associated with low early recurrence/residual cancer and accurate pathological staging. Patient summary: Following the first 3 yr of implementing a novel Quality Performance Indicator (QPI) programme in Scotland, we assessed compliance and outcomes in non–muscle-invasive bladder cancer. Evaluating over 4000 new bladder cancer patients, we found that the QPI programme was associated with low recurrence and accurate staging following the initial transurethral resection of bladder tumour

Effect of Robot-Assisted Radical Cystectomy With Intracorporeal Urinary Diversion vs Open Radical Cystectomy on 90-Day Morbidity and Mortality Among Patients With Bladder Cancer: A Randomized Clinical Trial

Importance: Robot-assisted radical cystectomy is being performed with increasing frequency, but it is unclear whether total intracorporeal surgery improves recovery compared with open radical cystectomy for bladder cancer. / Objectives: To compare recovery and morbidity after robot-assisted radical cystectomy with intracorporeal reconstruction vs open radical cystectomy. / Design, Setting, and Participants: Randomized clinical trial of patients with nonmetastatic bladder cancer recruited at 9 sites in the UK, from March 2017-March 2020. Follow-up was conducted at 90 days, 6 months, and 12 months, with final follow-up on September 23, 2021. / Interventions: Participants were randomized to receive robot-assisted radical cystectomy with intracorporeal reconstruction (n = 169) or open radical cystectomy (n = 169). Main Outcomes and / Measures: The primary outcome was the number of days alive and out of the hospital within 90 days of surgery. There were 20 secondary outcomes, including complications, quality of life, disability, stamina, activity levels, and survival. Analyses were adjusted for the type of diversion and center. / Results: Among 338 randomized participants, 317 underwent radical cystectomy (mean age, 69 years; 67 women [21%]; 107 [34%] received neoadjuvant chemotherapy; 282 [89%] underwent ileal conduit reconstruction); the primary outcome was analyzed in 305 (96%). The median number of days alive and out of the hospital within 90 days of surgery was 82 (IQR, 76-84) for patients undergoing robotic surgery vs 80 (IQR, 72-83) for open surgery (adjusted difference, 2.2 days [95% CI, 0.50-3.85]; P = .01). Thromboembolic complications (1.9% vs 8.3%; difference, -6.5% [95% CI, -11.4% to -1.4%]) and wound complications (5.6% vs 16.0%; difference, -11.7% [95% CI, -18.6% to -4.6%]) were less common with robotic surgery than open surgery. Participants undergoing open surgery reported worse quality of life vs robotic surgery at 5 weeks (difference in mean European Quality of Life 5-Dimension, 5-Level instrument scores, -0.07 [95% CI, -0.11 to -0.03]; P = .003) and greater disability at 5 weeks (difference in World Health Organization Disability Assessment Schedule 2.0 scores, 0.48 [95% CI, 0.15-0.73]; P = .003) and at 12 weeks (difference in WHODAS 2.0 scores, 0.38 [95% CI, 0.09-0.68]; P = .01); the differences were not significant after 12 weeks. There were no statistically significant differences in cancer recurrence (29/161 [18%] vs 25/156 [16%] after robotic and open surgery, respectively) and overall mortality (23/161 [14.3%] vs 23/156 [14.7%]), respectively) at median follow-up of 18.4 months (IQR, 12.8-21.1). / Conclusions and Relevance: Among patients with nonmetastatic bladder cancer undergoing radical cystectomy, treatment with robot-assisted radical cystectomy with intracorporeal urinary diversion vs open radical cystectomy resulted in a statistically significant increase in days alive and out of the hospital over 90 days. However, the clinical importance of these findings remains uncertain. / Trial Registration: ISRCTN Identifier: ISRCTN13680280; ClinicalTrials.gov Identifier: NCT03049410
